Antibacterial properties of resin composites and dentin bonding systems

Degree of Conversion and Antibacterial Activity of Total-Etch Versus Self-Etch Adhesive Systems

“…Agar-disc diffusion test method is a simple direct inhibition test and it has been most frequently used [9]. Addition of acidic monomers in large amounts for self-etching adhesive systems to promote adhesion, decrease pH values of these materials enough to kill or at least inactivate the bacteria [9]. The antibacterial effect shown by dentin bonding agents in this study may be related to their pH [7].…”

“…S. mutans and S. sobrinus are associated with the initiation of human dental caries, while L. salivarius is associated with the progression of the established lesion [7]. Agar-disc diffusion test method is a simple direct inhibition test and it has been most frequently used [9]. Addition of acidic monomers in large amounts for self-etching adhesive systems to promote adhesion, decrease pH values of these materials enough to kill or at least inactivate the bacteria [9].…”

“…Dentin bonding systems which possess antibacterial properties would be beneficial in eliminating the harmful effect caused by bacteria. Among different methodologies used to determine the antibacterial activity of dentin bonding systems, simple direct inhibition tests such as agar-disc diffusion methods have been most frequently used [8,9]. This research was conducted to compare the degree of conversion and antibacterial activity of the total-etch (etch-and-rinse) versus self-etch adhesive systems.…”

Nanomembrane Materials Based on Polymer Blends

“…Many efforts have been made in the design and fabrication of controlled organic/inorganic composites with novel properties, which include chemical, optical, electrical, biological, and mechanical properties [84][85][86][87]. For these hybrid systems, phase separation occurs naturally based on the fact that they are composed of two materials with totally different chemical characteristics [88,89].…”

Influence of a polymerizable eugenol derivative on the antibacterial activity and wettability of a resin composite for intracanal post cementation and core build-up restoration

“…Different antibacterial agents such as chlorhexidine, fluoride, quaternary ammonium salts and metallic agents (silver, gold and zinc) have been incorporated in acrylic based composite formulation in order to achieve this goal [10]. However, most of these additives cause an adverse effect in terms of mechanical properties, discoloration of the material [11], toxicity and short-term antibacterial effectiveness [12].…”
